Treatment

Stilicoderus maritimoides View in CoL n. sp.

Holotype (♂): Papua New Guinea, West Sepik, Vanimo,

Denake Range, km 12, 28.–29.X. 1992, leg. A RIEDEL ( SMNS).

Description

Body length ca. 4.2 mm. Proportions of holotype: length of head: 57; breadth of head: 62; diameter of eye: 22; length of antenna: 105; length of pronotum: 59; breadth of pronotum: 52; length of elytron: 70; breadth of elytra: 65; metatibia: 58; metatarsus: 37.

Pitchy black, labrum dark brown, mouthparts, antennae and legs rufo-testaceous, the femora infuscate but reddish-brown near apices.

Male: sternite VIII as in other closely related species. Aedoeagus see Fig. 9 View Figs .

Differential diagnosis

This new species, named in allusion to a slight similarity in the conformation of the aedoeagus, does not otherwise resemble S. maritimus (see ROUGEMONT 1986b) closely, being a smaller insect in all its proportions. Of the species of similar small size it differs from S. kolaensis n. sp. and S riedeli n. sp. in its dark femora, and from S. laticeps n. sp. in the dark femora and narrower head. It is externally virtually indistinguishable from S. sepikensis n. sp., S. riedelianus n. sp. and S. peninsularis Rougemont except, as from all other species, by the conformation of the aedoeagus.
